中文摘要:
      目的 配制适合硒化锌雾化施液化学机械抛光的最优抛光液。方法 选取氧化铝磨粒、pH调节剂四甲基氢氧化铵、氧化剂过氧化氢、表面活性剂聚乙烯吡咯烷酮为主要活性成分,以材料去除速率和表面粗糙度为评价指标,通过正交试验对硒化锌晶体进行精细雾化抛光,分析材料去除机理,并与传统抛光对比。结果 氧化铝质量分数为9%、pH值为11、过氧化氢含量为3.5%、聚乙烯吡咯烷酮含量为0.75%时,材料去除率较高,为923.67 nm/min,同时表面粗糙度较小,为2.13 nm。在相同工况条件下,传统抛光材料的去除率和表面粗糙度分别为965.53 nm/min和2.27 nm。结论 抛光液各组分对试验结果影响最大的为氧化铝磨粒,然后依次为氧化剂、pH值、表面活性剂。精细雾化抛光效果与传统抛光相近,但抛光液用量仅为后者的1/8。
英文摘要:
      The work aims to prepare optimum slurry for ultrasound fine atomization chemical mechanical polishing (CMP) of zinc selenide. With alumina abrasive, pH value regulator tetramethyl ammonium hydroxide, oxidant hydrogen peroxide and surfactant polyvinylpyrrolidone as main active ingredients, fine atomization CMP of ZnSe was carried out, and removal mechanism was analyzed through orthogonal experiment by taking material removal rate (MRR) and surface roughness (Ra) as assessment indicators. Then the experimental results were compared with those of traditional polishing. Provided that mass fraction of alumina was 9%, pH value was 11, hydrogen peroxide was 3.5% and polyvinylpyrrolidone content was 0.75%, the material removal rate was up to 923.67 nm/min and surface roughness was merely 2.13 nm. Under the same working conditions, the material removal rate and surface roughness of traditional polishing material was 965.53 nm/min and 2.27 nm, respectively. Among all constituents of the polishing slurry, alumina abrasive has the most influence on test results, followed by oxidant, pH value and surfactant. The effect of fine atomization polishing is similar to that of traditional polishing, but the consumed quantity of polishing slurry is only 1/8 of the latter.
